1 Measured with a no load capacitor.
2 Output hysteresis is defined as the change in the +25°C output voltage after a temperature excursion to −40°C, then to +85°C, and back to +25°C.
3 The operating temperature range is defined as the temperature extremes at which the device continues to function. Parts may deviate from their specified
performance.
